DUMP-WAGON.

Specification of Letters Patent.

I appncationaieaaprne,191s. seriaiNo. 759,962.

T o all 'whom it may concern:

Be it known that I, JOSEPH J. BYRON, a former subject of theKing of Great Britain, who have declared my intention of .be coming a citizen o'f the United States, 4and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Dump-VVagons, of which the following is a specification.

My invention relates to improvements in dump wagons and has.for its object the production of a wagon of this character which will be of durable and economical construction, one in which the dumping of the body of the wagon may be readily and easily effected, and in which the body may be readily and expeditiously returned to operative position after dumping, and further one which will be efficient in use.

Other objects will appear hereinafter. The invention consists inv the combinations and arrangements of parts hereinafter 'de- The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a side elevation of a dump wagon embodying my invention, Fig. 2 is a horizontal section taken on line -m'of Fig. 1,'Fig. 3 is a side elevation of the rearward portion of the wagon showing the body thereof in dumping position, Fig.r 4 is a front elevation of the wagon, Fig. 5 is a section taken on substantially line 'ys-y of Fig. 1, and Fig. 6 is an enlarged' fragmentary detail of the sprocket chain employed in the construction to effect swinging of the tail gate of the body of the wagon.

The preferred form of construction as Aillustrated in the drawings comprises a chassis 1 mounted upon wheels 2, a motor 3 of any approved design being mounted at the forward end of said chassis for effecting driving of the rear wheels of the vehicle in the propulsion of the latter.

The rearward end. portion-of the chassis 1 is fiat and horizontally disposed. Mounted upon said rearward portion of the chassis is the body 4 of the wagon which is mounted for freelongitudinal movement and, when said body is moved rearwardly to a sufficient extent, to permit of the tilting of said body to dumping position, as shown in Fig. 3.

in which said body is moved, that is' forwardly or rearwardly, depending of course upon the direction in which said shaft is rotated. Manual rotation of the shaft 7 as mentioned, is effected by means of-an endless sprocket chain 8 which passes around a sprocket wheel Q provided at one end of said shaft 7 and a sprocket wheel 10 which is mounted at the front end of the chassis l, as clearly shown in the several views. A crank handle 11 is connected with the sprocket wheel 10 for manual rotation thereof and hence of the shaft 7, and so with this arrangement it wil be s een that longitudinal movement of the body 4 in order to dump the same orto return the same to operative position after be- Ving dumped, may be effected by rotation of handle 11. The latter, as will be observed, is positioned in operative proximity with the drivers seat so that, in use, dumping or returning of the body 4 may be secured without the necessity of the driver leaving his seat. Provided at the opposite end of the shaft 7' is-a sprocket wheel 12 around which travels' an'endless sprocket chain 13 which also passes around a sprocket wheel 14 car.

riad by a counter-shaft 15 mounted in the chassis 1 toward the front end thereof. Splined tothe shaft 15 is a bevel gear 16 adapted to mesh with a bevel gear 17 which is fixed to the power shaft 18 of the motor 3, as clearly shown in Fig. 2. With this arrangement it will be seen that, upon movement of the bevel gear 16 into mesh with the gear 17, an operative connection will be established between the motor "3 and the shaft 7 thereby rendering it possible, if desired, to actuate the body 4 by the power of the traction motor of the wagon.A The bevel gear 16 is slid upon the shaft 15 into' and out of engagement with the gear 17 by means of a suitable switching mechanism or set of levers 19 which are connected for operation tndinal movement of the body 4 upon the chassis l, rollers 21 are preferably'provided the under side of the front end of said body which are adapted to contact with the upper side of said chassis when Said body is lo operatively positionedv thereon, as `clearly shown in F ig. l. At the front end of the bony 4, at either side thereof, are provided angular plates 22 the lower end portions of wbieh are inwardly turned in' order 'to engage under outwardly projecting flanges 23 seeured to the chassis l in order to lool the front end ofthe body 4 against relative up- Yrd movement when said body is posieil at' its forward terminal of movement Chassis.

f med end of the lever 24 is adaptl "en the body y4 is properly positioned upon the chassis' 1 to engage registering perforations provided in ears 26 and 27 provided respectively upon the front end wall i" f e body 4 and the adjacent wall of the ears beine so positioned that, ody 4 is in operative position, the 'ons thereof will be in registration i' other, as clearly shown invFigs. 1 l looking ofthe body 4 in order to of rearward movement thereof is efl by simply oscillating lever 24 to dis- 'e the lower end` thereof from said 2'? as will be readily understood. ided at the rear end of the body 4 is a ait 23 the lower edge of which is pivl l or hingedly secured to said body 4 at Fixed to the gate 28 at either side theretre sprocket wheels 3 0 which are arl`ed in alinement with the aXis of movesaid tail gate. Traveling'around ret wheels 30 are endless sprocket a -is 31, sprocket chains also passing -nd sprocket wheels 32 which are carbearing plates 33 adjustablymounted .ipon the opposite sides of the body 4, the @di 'stment afforded theplates 33 providineans for taking up any slack in the c zins 3i which may be caused through opr tion.

,nterposed in eeohef the 'chains 31 is an gated link or bar 34 provided with an ated longitudinally extending slot 35, arly shown in vFig. 6. The slots 35 of e links 34 are engaged by the upper ends which are rigidly/secured to ie opposite sides of the chassis l adjacent he rearward end thereof.` The arrangement s suon that, upon longitudinal movement of ywhich are pivoted at 3S at opposite sides @if l 1,087,723

the body 4 as for instance rearwardly, when said body has moved to an extent Corresponding with the length of the slots in the links 34, or until the tingersrll have traversed said slots the under sides of the chains 3l will be retarded by said fingers, and so that upon Continued rearward movement of the wagon body the chains 3l will move relative thereto to cause rotation of the sprocket .wheels 30 and hence swinging of the tail gate 2S to open position. Upon return movement of the body 4, reverse rotation of the sprocket wheels 30 and hence return swinging of the tail gate 23 will of course be effected Awhen said body 4 has `traveled forwardly an extent corresponding with the length of theslots 35 or when 'the lingers 36 have traversed the length of said slots, as'will be readily understood. The slots are elongated as mentioned, in .or-der to delay return or closing swinging ot the tailv gate 28 until the body 4 has been moved forwardly to such an extent that the frontend -will be dropped to normal position upon the lchassis, such return movement of said end of said body taking place of course when the center of gravity of said body passes thepivotal point thereof or the an of shaft 7 will be seen that upon movement of the body 4 to effect dumping thereof or returning of said body to position after having been dumped, the tail gate 28 will be automatically and simultaneously swung to open and closed positions. y rThe tail gate 28 is releasably locked closed position by spring held Catches 3 o the body 4 adjacent the rearward extremity thereof, said catches being adapted to engage loops 39 provided at the lateraledges of the gate,as shown in the -several views. Aotuation of the catches 37 is eieoted through the medium of flexible cords or cables 40 which are connected with the forward ends of said catches, said cords or cables passing forwardly over guide rollers and being connected at their forward ends with the respective extremities of a linl; 4l which is fulorurned at 42 midway its tremities upon thefront end of the body 4, as clearly shown in F ig. 5. The link 4l is in slotend-pin connection with the lever 24 so that upon rocking'of said lever said-link will be also rocked in order to draw the Cords or Cables 40 forwardly and hence rock the catches 37 to inoperative positions. 'With this arrangementthen, it will be seen that,

in use, upon rocking of the lever 24 in order to release the body 4 to permit o'ilf rearward movement thereof for dumping, the catches 37 will be simultaneously rocked order to #release the tail .gate to permit of the same swinging to open position.

Arranged at the .opposite sides'of the body VVit-h this arrangement then it llt) 4 are angular bars 43 the rearward upwardly turned ends'of which are rigidly secured as by screws or bolts to the opposite sides of the body 4 adjacent the rearward end there of. The forward ends of said rods 43 are secured by means of members 44 to the op.4 posite sides of the body 4, the members 44 being hingedly or pivotally connected with said rods 43 in order to permit the same swinging to the dotted line position, as shown in Fig. 3. The lower portions of the rods 43 extend parallel with the under side of thebody 4 spaced slightly therefrom, the same engaging under the shaft 7 `in order to serve as .a means of locking the body 4 in position or more precisely' to hold the racks 5 in mesh with the pinions 6. By hingedly connecting the forward end lpieces 44 with the forward. extremities of the rods 43, when it is desired to detach the body 4, the upper ends of said members 44 need only to be released from the vehicle body and swung to the dotted line position as shown in Fig. 3 whereupon said body may be moved rearwardly to such an extent as to disengage the same from the shaft 7, as will be readily understood. n*

In usirrg the dump wagon set forth then,

' when it is desired to dump the same, it is positions of adg'ustment. Upon rockingl ofv only required to rock the lever i4 which effects unlocking of the body of the vehicle and also the tail gate of said body, and then to actuate the handle l1 or the lever' 20 depending upon which form of power it is desired to utilize in the dumping. Upon rearward movement of the body 4, when the lsame reaches a position in which the center of gravity thereof passes rearwardly of the shaft 7, the rearward end of said body will drop downwardly causing said body to assume the dumping position shown in Fig. 3, the tail gate 28 in this-movement of the body being simultaneously` swung to open position. The returning of said body to operative position upon the chassis is effected by Simply rotating the handle l1 rearwardly or by reversing the driving of theshaft 1S through the usual clutch provided in the driving mechanism of the vehicle.' `W hcn the body has reached its forward terminal of movement upon the chassis the same may be locked in position' by simply tilting the lever 24, the latter being equipped with the usual pawl and ratchet `detent mechanism which engages with the conventional segmental rack for locking -said lever in its said lever 24 to operative position the catches 37 will be simultaneously released for movement to locking engagement with the tail gate under the influence of the springs co.- operating. with said catches.

. While l have illustrated and described the preferred form of construction for carrying mvjnventipp 'into edect, this is capable of variation and modification 'without depart;

ing from the spirit of the invention. l, therefore, do not wish to'be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the ap ended claims.
